      i will admit i had given up at gate 3 mostly due to life preventing me to put to much focus into it, but I did have fun.

        I was gonna watch this video but when I realised it was a walkthrough I decided to play the game myself instead of just spoiling it all.

                    Hey Mat Pat, can you do a walk through on how to do those things? Such as tuning up your screen brightness and the audio thing? I've tried looking up the screen brightness thing, but my computer seems to be different than the ones they show. Mine seems to have different controls. I know your a theorist, not a technician, but it would help me a lot. C'mon man, I can't do your challenge without it!

I miss when it was something fresh each time and mixed up. While I am also not a fan of those games at all, this isn't an attack, it's constructive criticism from a former fan, hope you take it as such.

                                                                            Have you thought about the implications? What if Hideo Kojima sees this video and it gives him ideas... Or the next Resident Evil uses this method for door locks? Game developers in the future burying all the content in more and more difficult ways, You've just raised the difficulty level on all the work you already currently do.....Won't someone think of the children!

                                                                                                Update: He's from Medina, Ohio, I'm from Ohio. I've literally competed against his old show choir. I can't believe I didn't know this before
